A discussion on the other site claimed that the fuck-up was in the copy that Universal sent to Mattel.
And that wrong websites frequently end up on packaging in other industries.
Mattel seem to be doing the sorry-dance for it, so no idea if it’s true. Though I’m sure Universal would be very keen to not be involved.
With a bit of luck, native RTC support means 2-way comms using reolink doorbells is close at hand.
